Abstract: A method of detecting high friction events in a laundry treating appliance includes rotating the drum, determining, during the rotation, a torque of the motor, an acceleration of the drum, a speed of the drum, and/or an angular position of the drum at each of multiple speeds, and repeatedly estimating with a parameter estimator, during the rotation, viscous friction, coulomb friction, and total friction based on the torque, acceleration, speed, and/or angular position of the drum. A high friction even is determined based on the estimated viscous friction, coulomb friction and/or total friction.

Abstract: Methods of reducing a likelihood of contact between a rotating laundry-container, such as a basket or drum, located within a tub of a laundry treating appliance where the method includes accelerating a rotational speed of the rotating laundry-container during an extraction cycle speed ramp, monitoring the friction associated with the rotating laundry-container during the speed ramp and comparing to a threshold and altering the accelerating of the rotational speed of the rotating laundry-container when the comparing indicates the threshold is satisfied.
